The new primary switched DC/DC converters with 250 W and 400 W output power of MTM Power GmbH are especially designed for automotive applications. They operate according to the push-pull principle, i. e. the input dc-voltage is chopped by two push-pull working transistors with a frequency of approx. 60 kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage (12 V or 24 V) is produced which is adjusted by pulse-width modulation according to the current mode principle. The series PCMD250W and PCMD400W are available with input voltages of 24 VDC (16,8…36 VDC), 80 VDC (50…150 VDC) or 110 VDC (66…154 VDC) and can be connected via screw connectors. The dimensions are 150 x 86 x 55 mm (L x W x H). Due to this compact design, they are also suitable for applications where only little space is available. The converters need no ground load, are maintenance free and short-circuit protected by primary and secondary power limitation. They are vacuum potted and prepared for the use in devices with Protection Class. As an option, they are available for the use in railway applications. Further features are a mechanically and electrically rugged design using SMD-technology and an automatic piece-by-piece test.

These primary switched DC/DC converters of MTM Power GmbH, the specialist of individual power supplies, are especially designed for automotive applications and operate according to the push-pull principle, i. e. the input dc-voltage is chopped by two push-pull working transistors with a frequency of approx. 70 - 100 kHz. With the help of a transformer and a secondary linear choke, a galvanically isolated output voltage is produced which is adjusted by pulse-width modulation according to the current mode principle. The converters need no ground load and are short-circuit protected by primary and secondary power limitation. The converters are maintenance free, vacuum potted, prepared for the use in devices with Protection Class II and fulfill the low voltage directive. They show a mechanically and electrically rugged design using SMD-technology and undergo an automatic piece-by-piece test. To ensure a smooth operation, it is necessary to mount the converters on a heat-dissipating surface.

The product family PMG/PCMG with DC input voltage completes the range of primary switched MTM Power Modules. The modules offer an input range of 20...72 VDC and allow - due to the different types available in this series - efficient solutions in numerous application fields. They are available with single, dual or triple outputs. The single and dual (sym.) versions are UL 60 950 and UL 508 approved. Dimensions are 90,5 x 65,5 x 33,5 mm for PCB-mounting (PMG) and 120,0 x 65,5 x 33,0 mm for chassis mounting (PCMG). Thus, they offer the same dimensions and pinning as the standard AC/DC and low voltage modules of the same wattage range which allows the customer to design only one layout for standard AC, low voltage and DC input. The vacuum encapsulated devices offer an isolation of 3,3 kVrms and comply to the up-to-date EN standards as regards CE conformity. Further features are rugged design, SMD-technology, automatic 100 % final test and 100-%-burn-in-test. The series PMG/PCMG offers 15 W or 30 W constant output wattage, is short circuit protected and needs no ground load.

MTM Power has developed a new generation of DC/DC converters with 80 and 150 Watt output power; these converters are especially designed for applications in vehicle and rail technology but also for use in industrial and telecommunication applications. This new model range allows input voltages of 9/14.4...154 VDC, in various voltage ranges, thereby covering all common battery sets. Typical input voltage ranges are, among others, according to EN 50 155, 14.4...33.6 VDC (24 VDC nominal), 21.6...72 VDC (36/48 VDC nominal) and 43.2...154 VDC (72/110 VDC nominal). Input voltage ranges deviating from these can be realised specifically for the customer at any time.
